Why do I not find any guys and get very frustrated by not seeing any results with my dating life?

In prior relationships and prior dating, I had no problem finding a guy that was attracted and now that I am older it has become increasingly difficult for me to find a man that is attractive. I tried finding guys in real life, but they did not want me since they were all tall. 'Tried both mainstream dating apps, like Tinder, Match. com, and disabilities dating apps as well but they all turned out to be scams and they all had the same type of users who were not attracted to me, but if I was, they wanted to fast. While I did try the Bumble app, it didn't go anywhere and I just deleted it. I then looked online for a real learning disabilities dating agency that was recommended by one of the Physical NHS employees.
